City Hall is considering selling or leasing 15 historic Baltimore landmarks, including the iconic Shot Tower and stately War Memorial building, which officials believe are underused and could bring the city sorely needed cash.

The idea has excited those who say the sites have been neglected and allowed to fall into disrepair. But some preservationists are worried about an uncertain future for buildings they hold dear.

"I've never heard about them thinking about anything like this," said Richard S.B. Smith Sr., director of the Friends of Orianda House in Leakin Park, one of the properties to be evaluated. "It blows me out of the water. It would be a shock to me and a loss to the community and the history of Baltimore."

City officials say their intention is to enhance the properties and turn them into profitable enterprises, but acknowledge that that might not be possible. Of the 15 buildings, 12 are protected by historic landmark designation, which requires developers to have their plans approved by a commission before making changes.

"All these landmarks are beautiful, and I hope we can put them to productive use," said Comptroller Joan M. Pratt, who supports the move to explore possible sales. "We have to decide whether we should dispose of them or maintain them. Some of them are very nice but require a lot of work."

Mayor Stephanie Rawlings-Blake's administration will ask the city's spending board to approve a $46,500 consulting contract Wednesday in which the Annapolis-based appraisal firm Westholm & Associates would determine the market value of the buildings. The city hopes to generate revenue from buyers or tenants who might have new uses in mind, such as turning them into offices.

The properties include such well-known sites as the Cylburn Mansion at Cylburn Arboretum, the Roland Park water tower and President Street Station.

"We're looking for strategies and options," said Thomas J. Stosur, the city's director of planning. "Should the city retain them? Should we lease them to existing tenants? Or should we try to sell some outright?"

Orianda House was once the summer home of millionaire inventor and railroad engineer Thomas Winans, who in the 1800s was considered the richest man in America. Smith said the property now houses the offices of Outward Bound, a leadership program. The building also is used for small weddings, church services and business meetings.

"To use the water tower for anything, you'd have to cut up the tank, which would be a tremendous pity," he said. "The tank is an integral part of the tower."

Other properties include the Upton Mansion, built in the 1830s, which has suffered decades of vandalism and neglect; the Gothic-style Clifton Park Valve House, finished in 1888, which sits in disrepair; and the Old Town Friends' Meeting House, which dates to 1781 and is the oldest religious structure in Baltimore.

Stosur said he didn't believe any potential buyers would choose to demolish the buildings, but acknowledged that some are not protected under laws governing historic properties.

The Superintendent's House in Clifton Park, the Public Works Museum and the West Arlington Water Tower are not listed in city records as having historic landmark status. Stosur said they could be protected for five years if a developer accepted a historic restoration tax credit.

"The idea is, by and large, to keep the historic property," Stosur said.

Stosur pointed out that the Peale Museum, the first planned museum in the Western Hemisphere, sits unused. The McKim Free School — built in 1833 as a replica of a Greek temple — has been used for recreational programs but needs significant repairs, he said.

"If it's just a vacant property sitting there, it's really kind of a liability for the city," he said. "Just having somebody inside of it would help the city. Hopefully, we could also earn some revenue off it as well."

He said a business, such as a law firm that frequently does work with City Hall, might want to set up shop in one of the landmarks. But Stosur doubted that any would be operated as a museum.

"That's not easy to find operating money for that kind of thing," he said.

Pratt noted that the city has worked for at least a decade to try to redevelop the Clifton Park Valve House. The administration struck a deal in 2002 with developer Charles T. Jeffries to turn the rare octagonal structure into offices, but yanked his contract in 2005 after he missed key deadlines.

Pratt said she believed the Valve House was one of the top prospects on the list for development.

"Clifton Park is beautiful," she said. "Maybe something could be done with that? Mr. Jeffries gave us a proposal and it did not materialize. There was interest in Valve House. Maybe there will be interest again."

Walter Horton, the comptroller's real estate officer, said it would be easier to find market uses for the buildings in good condition. He said it would be difficult to find profit in the rundown properties because a developer would need to sink so much money into them up front.

"You need millions of dollars to go into that building," he said of the West Arlington Water Tower. "We're asking the consultant, 'Tell us what you think we should and could do with some of these buildings.'"

Horton added that he is finalizing a lease agreement for the Shot Tower, but said he could not disclose details until the deal goes to the Board of Estimates.

Stosur emphasized that the contractor will merely provide independent analysis, and the city will make final decisions about how to proceed with the properties.

"There's nobody who has the time to take this on as a project who currently works in city government," he said.

Johns W. Hopkins, executive director of Baltimore Heritage Inc., noted that the 15 properties represent a wide range of buildings. Some are dilapidated and vacant, while others are well-kept and occupied.

"Many of the buildings on the list are iconic buildings that define their neighborhoods," he said. "Some even define the city of Baltimore. My hope is that the city is finding ways to be the best steward for these buildings. There are a lot of people in Baltimore who have put blood, sweat and tears into caring for these buildings. My hope is that decisions are made in as open a process as possible."

Republican Gov. Larry Hogan pledged bipartisanship and offered a conciliatory tone during his snowy inauguration Wednesday, promising "to create an environment of trust and cooperation, where the best ideas rise to the top based on upon their merit."

Advocates for programs spending state dollars on stem cell research or investment in technology companies were nervous about what Gov. Larry Hogan's budget would hold for them, given warnings of "strong medicine" to cure fiscal woes.

Calling it a first step toward fully restoring the death penalty in Maryland, Del. Pat McDonough said he plans to introduce a bill that would mandate capital punishment for anyone convicted of killing a police or correctional officer, a firefighter or witness during the performance of their duty.
